Favourite Friend Lyrics

Why does it have to be about a real friend? I think it's probably about his own alter ego, a younger self that does stupid stuff, and now he's done with it. But he knows it's the part of him that has the most fun, which is why there's so much pain and anguish in the song. Addiction? Perhaps.
